TELEPHONE-RECEIVER.

Patented July ii, rare.

Application filed May 3, 1915. Serial No. 25,352.

To all whom it may concern:

Be it known that I, WILLIAM WEIR HENRY, a citizen of the United States, residing at Wollaston, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Telephone-Receivers, of which the following is a specification.

This invention relates to telephone receivers and has particular reference to the mounting of the receiver so that it may perform the ordinary function of automatically closing a circuit and yet possess the desired freedom of motion with relation to the transmitter, without the use of an exposed cord.

I find, in practice, that the exposed cord offers opportunity to those evilly disposedfor removing and carrying off the receiver, while a rigidly secured receiver lacks that flexibility which is necessary to adapt it to the different demands that will be made upon it. Also, I find, from the stand-point of appearance, that it is desirable to conceal the mounting mechanism so far as is possible.

In the accompanying drawings, which form part of this specification and which illustrate one embodiment of my'invention, Figure 1 is a side view of a wall-set, partly in section, showing so much of the mechanism as is essential to a proper understanding of my invention. Fig. 2 isa fragmentary rear view, somewhat as it would appear from the plane 2-2 of Fig. 1. Fig. 3 is a fragmentary view of a modification.

The wall-plate 1 is mounted over the box 2 in anyordinary manner. On the front of wall-plate 1 is secured an ordinary transmitter 3. At one side of transmitter 3, preferably the left, a receiver 4 is suspended by means of a, preferably, semi-flexible conduit made up of the outer spring metal wrapping 5 surrounding and inclosin an ordinary cup-joint flexible tube 6. Of course, either the wrapping 5 or the tube 6 could be used alone, but I prefer to combine the two for the double purpose of stiffness and im ermeability, as will be later explained. lie opposite end of the conduit is permanently attached to a short curved pipe-section 7,

to which is attached an ear 8 adapted to form a pivot 9 which is the center of curvature of section 7 and also the pivot on which receiver 4 swings when in use. Pivot 9 is mounted in lugs 10, 10 which are here shown as a center.

as being fast to plate 1. In the rear of pivot 9 I mount a pin 11 adapted to automatically control the switch members 12 and 13.

The circuit wires are shown diagrammatically at 14 and terminate at binding posts 15, 15, in any ordinary manner.

A yielding bufi'er-post 16 is provided to receive the shock of the receiver when it is dropped after use. I 1

In operating my device, the receiver 4 is simply raised to the ear and dropped after using. As it is raised, pipe-section 7 gradually retreats within box 2, as indicated by dash lines in Fig. 1,

moving aroundpivot 9 At the upper end of its movement, pipe-section 7 abuts against the edge of opening 17 in plate 1 as a stop and if any further movement of receiver 4 is required, it is furnished by the flexible tube. With the receiver down, a shouldered portion 18 7% on pipe-section 7 serves as a stop and also as a complete closure for opening 17, thus excluding dust or moisture from box 9,.

By the combined use of spring 5 and tube 6 I secure greater stifi'ness and, also, tube 6 serves as a dust-proof case for the cord 14 as well as to prevent the insertion of a cutting tool which might otherwise be used to sever a strand of spring 5.

A stiff arm might be used instead of spring 5 and tube 6,

hinge joint 21 (Fig. 3) might be employed as I if the flexibility is not desired, or a combination of stifi' arm 20 and without departing from the spirit of my invention; but I prefer a universal flexibility which is best obtained in the manner illustrated in Fig. 1.

I do not limit myself to the precise con struction shown. I

What I claim is 1. A telephone wall-plate with an opening therethrough for the projection of the receiver-support; a receiver-support comprising a curved conduit pivotally mounted behind said wall-plate and adapted to project through said opening; a receiver pendantly mounted in connection with the pro jecting end of said conduit; and automatic means whereby said conduit may control an electric switch.

2. A telephone wall-plate; a receiver; a rigid conduit pivotally mounted on the back of said wall-plate and adapted to project therethrough and be connected with said re- .ceiver; and means whereby the raising or lowering of said receiver may respectively cause said rigid conduit to withdraw or extend through said wall-plate.

3. A wall-plate with an opening; a rigid conduit adapted to project therethrough;

receiving means connected with said conduit; and a pivot for said conduit and so positioned as to cause said conduit to withdraw or extend through said opening when said receiving means is manipulated.

4. A wall-plate with an opening; a curved conduit adapted to extend or withdraw through said opening; and a pivotal mounting for said conduit, positioned at substantially thecenter otcurvature of same, and adapted to guide said extension or withdrawal when said conduit is manipulated.

5. A wall-plate with an opening; a curved conduit-adapted to extend or withdraw therethrough around its axis of curvature as a center; guiding means for holding said a conduit within its path of motion; and a sound conveyor connected with the projecting end of said conduit and adapted, when properly manipulated, to cause said extension or Withdrawal.

6. A telephone receiver; a wall-plate with an opening; a curved conduit adapted to extend or withdraw through said opening and around its axis of curvature as a center; guiding means for maintaining said conduit in its path of motion; and means for mounting said receiver so that its manipulation may cause said extension or withdrawal.

7. A telephone wall-plate with an opening therethrough; a receiver; a curved conduit adapted to project through said open ing; means for connecting said receiver with said conduit; and a pivotal mounting for .said conduit and so positioned as to permit the extension or withdrawal of said conduit through said opening and about said pivotal mounting as a fulcrum.

8. A telephone wall-plate with an opening; a receiver; a rigid conduit pivotally 4 mounted in connection with said wall-plate and adapted to be connected with said receiver; and means whereby the raising or lowering of said receiver may cause said conduit to withdraw or extend through said wall-plate. In testimony whereof, I have afiixed my signature in the presence of two witnesses.

WILLIAM WEIR HENRY.
